MACHINE FOR MAKINGl CHANGE.

To all wiz-omet may concern A Be it known that I, ERNEST W. RUSSELL, acitizen of the United States, residing at Vallejo, in the`count-y ofSolano and State of California, have invented new and usefulImprovements in Machines for Making Change, of which the following is aspecifi-v cation.

I-n view of the general use of automatic,

vending machines a necessity 'has arisen for a' mechanism for makingchangeso that a' coin of proper value may be obtained by a persondesiring to operate a vending machine and not 4having at hand a coin ofprescribed value.

rThe invention provides amechanism which may be used independently of orin connection with a vending machine, the purpose being to enable aperson upon deposit-.ing a coin in the machine to obtain the valueAthereof in change, thus for instance a silver dollar deposited in themachine will result Ain a return to the operator of four quarters and atwenty-tive cent piece of five five cent pieces, and a nickel of fiveone cent pieces. .It is to be 4understood that the machine mayembodysimilar change making mechanisms one for a silver dollar, `one forahalf dollar, one for a quarter dollar and one -for a five cent piece ornickel, the change making mechanisms being similar but varying in size.

A further lpurpose 'of the invention is the provision of a change makerwhich will operate only 1n connection wlth a coin of prescribed value, acoin of less value failing to make proper connection for operation ofthe mechanism and a coin of greater value v not being permitted to enterthe coin slot.

The mechanism also embodies novel means whereby ample provision is hadfor release of the operating coin and a discharge of the change, therebypreventmg the same com being used -for operating the machine a sec-Specification of Letters Patent.

similar -to Fig. 1, the parts being in section. Fig.- 31is la -top planview. Fig. 4 is a yhorizontal section on the line of Fig. 1. Fig. 5 is atransverse section on the line g/i-y/ of Fig. 1. Fig- 6 is a verticalsection on the line w-w of Fig. 3. Fig. .7`is a detail view Ainperspective of the hollow abutment.

`Corresponding and like parts are referred to in the following`description, and indicated in all the views of the drawings, by the samereference characters'.

The change making mechanism illustrated is adapted for delivering i'iveone cent pieces for each Ifive cent piece deposited in the machine.A Theoperating parts are supported upon a plate 1, which may be fitted to thecasing or cabinet 2 in any manner or relative position according to thespecific application of the change maker. rlhe magazine for receivingthe one cent pieces or coins to be delivered in change is indicated at 3and may be of any length or diameter v to meet existing conditions. Themagazlne 3 is elevated Aorsp'aced from-the plate .-1 a

distance corresponding to the depth of the pile or number of coins to bedelivered` in change at each operation of the machine. A tube'4 leadsfrom an opening in the plate 1 to an opening in the front of the casingor cabinet 2 and serves to direct the change into a cup 5 arranged uponthe front of the casing opposite the delivery end of the tube 4. Thereceiving end ofthe tube 4 is out of line with the magazine 3. A coinejector 6 is pivoted between its ends to the plate 1 and has a pocket atone end arranged to ,register with the magazine 3 and with fthe tube 4,the pocket being of a diameter corresponding tothe diameter of the cointo be delivered in change and equal in depth lto the pile or number ofcoins to be delivered at each operation. The coin ejector 6 operatesover the plate 1 and below the magazine 3 and in one position its pocketregisters with the magazine and in another position it registers withthe opening in the plate 1 'in register with the re-- ceiving end .ofthe tube 4 so Vas to deliver the change into said tube. The magazine 3'has a vertical slot 7 formed in a' side to receive an extension 8projecting laterally from a weightz9, which is supported upon the pileof coins containedA in themagazine 3. Theweight 9 is connected by meansof ai. Y wire 10 with one pole of a battery 11, the

opposite pole of said battery being connected bymeans of a wire 12 witha contact 13 arranged to be engaged by the extension 8, whichconstitutes a movable contact. alarm 14 is located in the length of thewire 12 so as to give warning when the magazine is nearly or quite emptyso that the same may be replenished with change. A chain or flexibleconnection 15 is connected with the weight 9 and passes over a' guide 16and has a counterweight 17 attached to its opposite end, saidcounterweight being arranged to operatel in a casing 18 mounted upon theplate 1 or inany convenient manner. The purpose of the counterweight 17is to take up any slack in the chain or connection .15., i

A flattened tube 19 extends from a -coin slot formed in the front of thecasing and an opening formed in the plate l and constitutes the coinwayfor directing the coin -deposited in the machine to the change operatingmechanism. A coin receiver 20 is located at the inner or delivery end ofthe coinway 19Jand is of cylindrical form and closed at opposite ends.The coinway 19 connects with one end of the coin receiver to deliver thecoin thereto. The lower portion of the coin receiver is cutaway, formingan opening 21 through which the coin is discharged. A guide 22 isarranged opposite the opening v21 of the coin receiver to give properdirection to the coin in its delivery. A spring actuated plunger 23 isarranged -to operate through an opening formed in the front ofthe'casingv 2 and through an opening formed in the outer end of the coinreceiver 20. The inner end of the plunger 23 clears the outer end of thecoin receiver so as not to obstruct the entrance of the coin thereinfrom the coinway y19. After the coin has been received in the part 20 apressure upon the plunger 23 forces the coin rearward in the receiver 20and operates the change mechanism. A hollow abutment 24 is arranged tooperate within the coin receiver 20, its outer diameter correspondingwith the diameter of the prescribed coin adapted to operate themechanism. The. lower portion of the hollow abutent is ycutaway, asindicated at' 25, for the discharge of the coin, said cutaway portioncorresponding with the'opening 2l in the lower front portion of the coinreceiver. A spring actuated stem 26 is connected with the hollowabutment 24 and normally holds the latter projected. The front end ofthe hollow abutment' is spaced from the front end of the coin receiver adistance to receive the operating coin. In the event of the coindeposited in the coinway 19 being of a less diameter than the prescribedcoin designed for operating the machine it will pass through the hollowabutment 24 upon pressing the plunger 23 inward and AIL dischargethroughthe openings 25 and 21. However, when a coin of predetermined value isdeposited in the coinway 19 and enters the receiver 20 it engages thefront end of the hollow abutment 24 upon pressing inward upon theplunger 23 and moves said hollow abutment and the spring actuated stem26 connected therewlth inward and operates the change mechanism. Thecoin ejector 6 has the end opposite that provided with the pocketarranged to engage the stem 26 so as to move therewith. Rearwardmovement of the hollow abutment 24 edects a movement of the coin ejector6 to4 cause a delivery of the change contained in the pocket thereofinto the delivery tube 4. The parts have a prescribed movement and whenthe plunger 23v has reached the limit of its inward movement the hollowabutment 24 is engaged by means of a dog 27 so that when the plunger 23moves outward the operating coin is released and drops into a receptaclearranged within the cabinet to receive the same.

The dog 27 is pivoted between its ends tothe plate l and one endoperates through an opening formed in a side of the coin re-` ceiver 20and is adapted to engage a shoulder 28 on a side of the hollow abutmentto hold the latter at the limit of its inwardmovement until the dog 27is stripped of the plunger 23 when reaching the limit of its` outwardmovement. A link 29 connects the dog 27 with one end of a lever 30, theopposite end of said lever` being connected to a plate 3l in which isformed a longitudinal slot 32 in which is arranged to operate a pin 33carried by the plunger 23. A spring 34 normally exerts a pressure uponthe dog 27 to throw its inner end in engagement with the shoulder 28 theinstant said shoulder clears the dog. As the plunger 23 reaches thelimit of its outward movement the pin 33 engages the outer end' of theslot 32 and moves the plate 3l outward and trips the dog 27 and releasesthe hollow abutment 24, which springs forward by the i action of thespring arranged to coperate with the stem 26.

The receptacle 35 arranged within the cabinet has its front Hush withthe front of the cabinet and covered by a piece of plate glass so as toexpose a number of coins. The bottom of the receptacle 35 is movable andcounterbalanced so as to support a number of coinsin position -forobservation and when the weight of a vgiven number of coins overcomesthe counterbalance of the bottom 36 said bot-tom swings downward anddelivers the coins into the receptacle. The bottom 36 is pivoted and isnormally retained in position bymeans of a weight 37., By retaining anumber of the coins in view a person vis deterred from making an attemptto operate the machine by means of a slug or dummy.

The change mechanism may be located in any convenient position and anynumber of mechanisms may be provided according to the coins for whichchange is to be given. To operate the machine a coin 38 of prescribedvalue is introduced into the coinway 19 and is directed thereby into thecoin receiver 20 between the inner end of the plunger 23 and the frontend of the hollow abutments 24. Inward pressure upon the plunger 23causes rearward movement of the hollow abutment 24 and its springactuated stem 2G, thereby operating the coin ejector whereby the coinsrepresenting the change are withdrawn from the lower end of the magazine3 and delivered into the tube 4and directed by said tube into the cup 5.lVhen the plunger 23 reaches the limit of its inward movement the dog 27engages the hollow abutment 24; and prevents the same following theplunger 23 and asa result the coin 3S is released and drops through theopenings of the coin receiver and hollow abutment into the receptacle35. As the plunger 23 reaches the limit of its outward movement theplate 31 is tripped and releases the hollow abutment'which springsoutward and at the same' time returns the coin ejector into position toreceive the number of coins representing the change to be delivered atthe next operation of the machine upon depositing a coin 38 into thecoinway 1S) and pressing inward upon the plunger From the foregoingdescription, taken in connection with lthe accompanying drawings, theadvantages of the construction and of the method of operation will bereadily apparent to those skilled in the art to which theinventionappertains, and while I have described the principle of operation of theinvention, together with the device which I nowl consider to be theembodiment thereof, I desire to have it understood that the device shownis merely illustrative and that such changes may be made when desired asare within the scope of the claims appended hereto Having thus describedthe invention What is claimed as new, is

In coin operated mechanism, the combination of a coin receiverA having adischarge opening in its lower portion at a point between its ends, ahollow abutment slidably mounted within the coin receiver, meansnormally pressing the abutment forwardly, a manually operable memberarranged to enter the coin receiver, a coinway arranged to deliver acoin into the coin receiver between the manually operable member and theabutment, a projection at one side of the hollow abutment, a dogarranged to travel upon said projection and to engage an end thereof tohold the abutment in retracted position, a member having a limitedmovement with reference to `themanually operable member, and connectingmeansbetween the said dog and the last mentioned member to admit of thesaid dog beingtripped when the manually operable member is near thelimit of its return stroke to effect release of the abutment.

In testimony whereof I allix my signature in presence of two witnesses.
